利用ATLAS探测器在质子-质子碰撞中记录的双μ子事件，对接触相互作用进行了研究。数据样本对应于的积分光度。在双μ子质谱中未观察到与标准模型的显著偏离，允许以下95% C.L.接触相互作用的能量尺度上的限制：（4.5 TeV）的建设性（破坏性）在左左isoscillation复合模型的干扰。这些限制是迄今为止对接触相互作用最严格的限制。
A search for contact interactions has been performed using dimuon events recorded with the ATLAS detector in proton-proton collisions at. The data sample corresponds to an integrated luminosity of. No significant deviation from the standard model is observed in the dimuon mass spectrum, allowing the following 95% C.L. limits to be set on the energy scale of contact interactions:(4.5 TeV) for constructive (destructive) interference in the left-left isoscalar compositeness model. These limits are the most stringent to date forcontact interactions.
